Extended Data Fig. 1 SRC pair breakup.
Diagrammatic representation and four-momentum kinematics of the two-nucleon knockout A( e , e ′ Np ) reaction within the SRC model. The dashed red lines represent off-shell particles and solid black lines represent detected particles. The A −2 system is undetected.
a – c , Comparison of the number of A( e , e ′ p ) event reactions versus the ( e , e ′ p ) missing momentum p miss ( a ), Q 2 ( b ) and x B ( c ). d – f , Comparison of the number of A( e , e ′ pp ) event reactions versus the ( e , e ′ p ) missing momentum p miss ( d ), Q 2 ( e ) and x B ( f ). The total number of counts in aluminium (cyan), iron (orange), and lead (purple) was scaled to match that of carbon (dark blue). The shaded bands indicate the 1 σ statistical uncertainty of the data.
Extended Data Fig. 3 Momentum-transfer and missing-momentum angular correlations.
a – d , Distribution of the relative angle between the momentum transfer q and the ( e , e ′ p ) missing momentum for A( e , e ′ p ) ( a , b ) and A( e , e ′ pp ) ( c , d ). The panels at left compare the 12 C data and GCF calculations using different NN interaction models ( a , c ); and the panels at right compare the data for carbon (blue), aluminium (cyan), iron (orange), and lead (purple) nuclei ( b , d ). The total number of counts in the aluminium, iron and lead data has been scaled to match that of carbon. In a and c , the width of the band and the data error bars show the model systematic uncertainties and data statistical uncertainties, respectively, each at the 1 σ confidence level. The shaded bands in b and d indicate the 1 σ statistical uncertainty of the data.
Extended Data Fig. 4 Electron and proton kinematics.
Momentum and angle distributions of scattered electrons and protons for 12 C( e , e ′ p ) ( a , c , e , h ) and 12 C( e , e ′ pp ) ( b , d , f , g , i , j ) events. Coloured bands show the various GCF calculations. The width of the shaded band and the data error bars show the model systematic uncertainties and data statistical uncertainties, respectively, each at the 1 σ confidence level.
Extended Data Fig. 5 Kinematic correlations of 12 C( e , e ′ p ) events.
a , Q 2 versus the missing-momentum distribution of 12 C( e , e ′ p ) data. Owing to the event selection criteria, as p miss approaches 1 GeV/ c , the minimum Q 2 of the data approaches 3 GeV/ c . b , E miss versus p miss of the 12 C( e , e ′ p ) data. The red line indicates the expected E miss – p miss correlation for the breakup of a stationary pair.
The relative momentum distributions for different NN interaction models studied in this work, for pn ( a ) and pp ( b ). c , The momentum dependence of the fraction of protons belonging to pp SRC pairs in 12 C.
a – j , As in Fig.3a–j. k , l , The reconstructed initial light-cone momentum fraction carried by the struck nucleon for ( e , e ′ p ) ( k ) and ( e , e ′ pp ) ( l ) events. m , The total pair light-cone momentum fraction for ( e , e ′ pp ) events. The data points are identical to those in Fig. 3a–j. The bands are different and show the results of the GCF calculations using light-cone formalism and various NN interaction models. The width of the shaded band and the data error bars show the model systematic uncertainties and data statistical uncertainties, respectively, each at the 1 σ confidence level.
Extended Data Fig. 8 Scale dependence and non-local interactions.
a – c , As in Fig.3a, b ( a , b ) and Fig.2a ( c ), but also including the non-local N3LO (600 MeV/ c ) interaction. The width of the shaded band and the data error bars show the model systematic uncertainties and data statistical uncertainties, respectively, each at the 1 σ confidence level. See Methods for details.
